Update Notes

1. Update is for serial numbers manufactured starting with MK071019R only.  Units prior to these serial numbers cannot update the weld module software, so the update will not work correctly.
   
   
2. For units that meet the serial number requirement, the update will end with a "WELD COMM" error on the display. The update will be loaded properly, but the weld module does not start.  To remedy this, simply turn off the engine, wait for 10 seconds, and restart.  The unit should operate properly.

Release Notes for Bobcat 200 Air Pak Models (Release M): 

• Bug Fix: Customer CAN message could conflict with control board boot loader
• Bug Fix: Incorrect air compressor hours in summary file
